Choosing the best path: Global to national coordinate transformations
Joel Haasdyk and Dr Volker Janssen
Recently a number of new transformationparameters have been published, allowing users to transform data between national Australian datum (GDA94) and the global (dynamic) ITRF datums. This has created a problem of choice because there are many different paths of transformation by which data can travel between these datums. This paper have demonstrated that differences of up to a few centimetres in each coordinate component can occur depending on the choice of the transformation method applied between both... [more] |
